How do i make the camera in a scene look "low quality"?
There's many ways to achieve a low quality camera look, and as already covered in the comments, the most convenient ways to do so are low quality settings of the render: low resolution, low FPS if it's an animation, low sample amount, high compression of the image, resigning from filmic color space, and choosing many other sub-optimal or outright incorrect settings.
The actual challenge is to simulate a low quality camera realistically.
Motion blur
The easiest aspect to explain is exposure time: when you render an image in Blender, even in an animation, for each frame, all objects stay perfectly still and are rendered as such. Therefore even a flying helicopter's propeller will look still on a single image. Meanwhile, no camera is stopping the time while taking the picture, and most cameras will produce a visible motion blur:

You can enable Motion Blur in Render Properties tab, but contrary to the advises in the first paragraph, it will increase the render time.
Aliasing
Somewhat similarly, a digital camera has a sensor, which doesn't react to every single photon hitting it, but rather has a well for each subpixel, which collects photons, generating electrons inside, and then an electronic circuit calculates the subpixel value based on the charge density. This produces an averaged value of brightness for a given region. Meanwhile Cycles renderer works in an opposite way: not only it shoots a light ray outwards from the camera, but, more importantly, it's a single ray. A real camera recording a checkerboard moving away, will eventually perceive it as gray, as light coming from both black and white squares will hit the same well on the sensor.

I was able to render it with Cycles, because the default number of samples was enough to average the colors. However, watch what happens if I render with just 1 sample for each pixel:

The takeaway here is that the noise in Cycles is not the same as noise in a cheap camera - you won't get some artifacts like fireflies in a real camera. If you want to get a realistic grain effect, you have to use a high sample count and wastefully add the grain in post-processing. As far as I understand, the grain is a result of dithering data into a limited color space and then increasing the contrast, which moves these colors apart.
